The difference between High temperature Silicone and heat resistant plaster

Posted by sophiamilller on September 20th, 2013

High temperature Silicone and heat resistant plaster are materials which are used in situations when high levels of heat are present in the environment. These materials are used in place of usual silicone and plaster when there’s a chance that they will be subjected to high temperatures or hot surfaces. A typical application for the High temperature Silicone is to serve as a protective coating of a ventilation duct, while the heat resistant plaster finds application in areas such as the opening of a cassette fireplace. Both materials are used in construction, and both materials boast high levels of heat resistance. However, that’s where the similarities between High temperature Silicone and heat resistant plaster end.

The materials differ in their specific area of application, and in many physical and chemical properties. The plasteris not a suitable substitute for High temperature Silicone, and this goes both ways. Similarly, you can’t use the Silicone in place of plaster. Heat resistant plaster has properties very much like the usual plaster. It also has a very similar field of application. In fact, it is often used instead of the gypsum plaster, especially in domestic situations. The most typical sphere of application ofresistant plaster is replacing the usual plaster in the areas of intense heat, for instance, adjacent to wood burning stoves and gas cookers, or around the opening of fireplaces.

The usual plaster would not live long in such a place, as the high temperatures can cause it to crack and ultimately fall of the wall, but the heat resistant plaster fares just fine. The plaster can also be used for many other purposes. It can be used as a decorative element for an oven, to protect other materials with different heat resistance properties from high temperatures, and it has limited use as a fire prevention material or for when you have to prevent heat loss.

High temperature Silicone, on the other hand, is often used as a heat resistant sealant or as a protective coating for parts that may be subjected to intense heat. The silicone is designed to serve as a bonding agent in high temperature environments, so it will not use its adhesive properties (which are good by themselves, and in some situations you can use High temperature Silicon as a substitute adhesive) and will not become brittle from protracted exposure to heat.

The materials that are best used for bonding with silicone are glass and glazed surfaces, enamel, ceramics, impregnated and painted wood, wood, and most plastics. The other application for heat resistant silicone is to serve as a protective coating for parts used in a high-temperature environment. The typical list of domestic parts that can benefit from such coating includes heating units, chimney filters, kitchen appliances, pumps, motors, smoke and ventilation ducts, boilers, flues, stoves, fireplaces, coolers, and power units.

If you’re in a situation where heat-resistant coating is needed, use heat resistant plaster in place of usual plaster or High temperature Silicone for many other situations.
